It's no surprise the famous family have a number of luxury cars to choose from, but today, the two E! stars chose a pair of vehicles that are each a, well, convertible coupe, if you will. Continuing in their playful ways, the two brunette beauties posed in toy cars for a funny Instagram photo.

Kardashian posted a similar photo of the duo and wrote, "I dare you to catch us riding dirty!!!!"

When Khloé isn't sexing up a toy fire truck, she's adding beauty to the cover of Cosmopolitan's April 2014 issue. Aside from the sexy photo shoot, the 29-year-old opened up to the publication about her dramatic past year.

"I'm not a big 'cry on a shoulder' person," she explained. "I'm very introverted when it comes to my own stuff. Everyone has issues and I'm not someone who liked to burden people…I hold things in. I don't know why."

And even with her marriage ending, she filed for divorce from NBA star Lamar Odom back in December, Khloé maintains that she "wouldn't change a thing."

"Your life is meant for you to understand and process, not to make anyone else happy," she told the mag. "I don't have any regrets…you learn as you go."
